SMOKING PIPE GB, TUBE.

Application filed June 4, 1924.

This invention is for a smoking pipe, or smoking tube.

It is generally recognized that tobacco smoking is more enjoyable if the smoke can be cooled to an appreciable extent, before it reaches the mouth, and this is particularly true in connection with pipes. In order to effect cooling of the smoke, pipes with extremely long stems are made. ther forms of pipes have been devised wherein the smoke passage extends back and forth inside the pipe stem. As heretofore made, however, the back and forth passages have all been so arranged that efficient cooling is not obtained, the various passages generally bc ing in a solid block of material, so that all are heated to substantially the same degree by conduction, and with very little extra radiating'surface really being provided.

The present invention has for its principal object to provide a smoke tube, in either a pipe stem or cigar or cigarette tube or holder, a novel conduit for the smoke which may provide, in a pipe or holder of ordinary length, a smoke passage equal to several times the length of the stem with substantially the entire length of said conduit exposed, and out of contact with adjacent portions of the conduit, whereby a large radiating surface and effective cooling may be obtained.

A further object of the invention is to provide a simple way of constructing this smoke conduit and permit of its being cleaned.

A further object of the invention is to pro vide a convertible pipe, cigar, and cigarette holder of novel construction.

These and other objects and advantages are attained by my invention, which may be understood by reference to the accompany" ing drawings, in which Fig. 1 is a side view, partly in section, of a pipe embodying the invention.

Fig. 2 is a transverse section in the plane of line IIII of Fig. 1.

F ig. 7 is a side. view of a further modification of the invention.

Fig. 8 is a top view of the bowl of the form shown in Fig. 7.

Fig. 9 is a detail view of a smoke dis charge nozzle that may be used in connection with the pipe.

Referring first to the construction shown in F igs. 1 to 5, inclusive, of the drawings, 5 designates the bowl of a pipe having a hollow stock 6 and a detachable mouth} iece 7. Leading out from the bowl of the pipe, is a removable tube, preferably of aluminum, similar to that now commonly used in pipes, but considerably longer. This tube, designed generally as 8, is bent back and forth upon itself several times, with eacl length out of contact with the others, several lengths thus being provided. I prefer to have five such lengths, as this number fits well into a fair sized stock. The length leading from the bowl is designated 9, and the central length leading into the stem, into which its end is slidably fitted, is designated 10. The intervening lengths are des ignated 11.

As before stated, each length is preferably out of contact with the other lengths, and preferably, but not necessarily, out of contact with the interior of the stock. The entire tube may be removed upon removal of the mouth piece 7.

The outside wall of each curve in the tube or conduit, is cut away, as indicated by the dotted line in Fig. 4, and as shown in Fig: 5, so that the entire curve may be accessible for cleaning, and a straight, flexible pipe cleaner of the usual type inserted at one-end of a length 9, 1O orll and projected from the other end.

A suitable cap, however, is provided for each opening to make it substantially air tight in use. A form of such cap is shown in Figs. 5 and 6. The cap 12 is of suitable shape to conform to the curvature of the tube, and ma have integral prongs 18 thereon oppositely disposed with respect to each other and slightly curved to en'ibrace the tubing. The inherent resilience of the prongs holds the cap tightly, but rcleasably on the conduit. In order to prevent them from being lost, each cap may have a hinge 1d at one end thereof, through which a wire or clip 15, extending around the conduit. passes to pivotally retain the cap in place.

IOU

Each cap may have a cork sealer or gasket 16 on its inner face, to insure a tight joint.

it removable cap of this KillCi provides a simple and etlicient closure that enables the tube to be easily clean d '7" i is a highly desii when necessary. ini ble feature, because, due to the greater condensation in the cool smoke, more liquiijl will accumulate in the p1 pe.

Because it is desirable to have as little l-OlS l-ll16 collect in the pipe as possible, I may fit the hollow shank 17 of a hollow, cly perforated button 18, best shown in 9, into the mouthpiece. This will tend L vent much of the saliva from the mouth from entering the pipe, whereas a single large opening, as generally provided, will not.

In the form of the invention shown in Fig. 6, the bowl 20 of the pipe does not have the usual integral stock, but is provided with a short extension 21 to which the jointed stem hereinafter described attaches.

This stem comprises a tubular body 22 and a separable mouthpiece 23, between which may be a heat insulating connector 24. The body 22 has a socket 25 in its forward end and a chamber 26 in the main portion of its length. The socket 25 is shaped to receive the end of a cigar, so that, by detaching the bowl, the stem may be used as a cigar holder.

This socket is supplied with a removable plug 27 that has a recess 28 therein of such shape and size that it may receive the end of a cigarette. Thus, the article is a con vertible pipe, cigar holder and cigarette holder.

In the chamber 26 is a tube or conduit 29 in all respects similar to tube 8 described in connection with Fig. 1. The metal tube can be readily, removed for cleaning.

In both forms of the invention already described, suitable openings are provided in that portion of the stock or body of the stem to allow for the free circulation of air around the metal tube. Small openings for this purpose are indicated at 30 in both figures and a single large opening at 31 in each figure.

In 7 and S, the bowl 32 of the ipe is joined to the stem 33 which has a be low interior. The end of the stem projects into the body of the pipe, the stem having a slot 3a in each side, the slots beginning at the end which joins onto the pipe and extending short distance along the stem.

A metal smoke tube 35 extends from the bowl along the interior of the hollow par of the stem, and then turns back on itself. The return length emerges from the stem through one of the slots 534i and the tube then extends up and down around the bowl, as indicated at 36, finally re-entering the stem through the other slot and extending therealong to the free end f the mouthway lengths for leaning.

in order that the cooling may be more effective in the form of device illustrated in Figs. 7 and 8, the interior of the pipe may have a central liner of wood or other sum able substance, outside of which is a wall of suitable leat insulating material. tihis arrangement serves to keep the bowl with which the tube contacts cooler the it otherwise would be. If desired, the bowl could be formed of metal with the liner $38 of wood.

The slotted construction of the stem. 3i, enables the stem to be removed to give access to the smoke tube.

While I have described the invention as being particularly applicable to pipes, it will readily appreciated that it is equally ap plicable to other smoking appliances, as cigar and cigarette holders. it will be further understood that the term pipe hereinafter used in the claims shall be construed to cover cigar and cigarette holders.

Various changes and modifications other than those illustrates may be made within the contemplation of my invention, and under the scope of the appended claims.
